Abstract

Devices, systems, and methods appropriate for use in medical training that include materials that better mimic natural human tissue are disclosed. In one aspect, multi-layer tissue simulations are provided. In another aspect, male genitalia models are provided. In another aspect, abdominal surgical wall inserts are provided. Systems and methods associated with these devices are also provided.

First claim

What is claimed is:

1. A multi-layer tissue simulation, comprising:
a simulated skin layer;
a simulated fat layer secured to the skin layer;
a simulated fascia layer secured to the simulated fat layer, wherein the simulated fascia layer comprises a sheet of spunbonded olefin material;
a simulated muscle layer secured to the simulated fascia layer; and
a backing layer secured to the simulated muscle layer.

2. The multi-layer tissue simulation of claim 1 , wherein the multi-layer tissue simulation represents a portion of at least one of gluteus tissue, deltoid tissue, or thigh tissue.

3. The multi-layer tissue simulation of claim 1 , wherein the simulated skin layer comprises a silicon material having a first hardness and the simulated fat layer comprises a silicon material having a second hardness, the second hardness being less than the first hardness.

4. The multi-layer tissue simulation of claim 3 , wherein the simulated fat layer comprises a silicon foam.

5. The multi-layer tissue simulation of claim 1 , wherein the simulated skin layer and the simulated muscle layer comprise a common silicon material.

6. The multi-layer tissue simulation of claim 1 , wherein the simulated fascia layer is secured to the simulated fat layer with a silicon adhesive.

7. The multi-layer tissue simulation of claim 1 , wherein the backing layer is pigmented to match the simulated skin layer.

8. The multi-layer tissue simulation of claim 1 , wherein the multi-layer tissue simulation is sized and shaped for positioning within an opening in a portion of a manikin.
